4. Close auxiliary evacuation valve and shut off auxiliary
evacuation device.
5. Note and record absolute pressure gage reading.
6. Coat all machine field-welded joints with weld sealant.
MOUNTING THE BURNER
The burner is shipped and installed as 3 separate sub-
assemblies (Fig. 11):
• front plate and refractory assembly, which is attached to
the generator
• burner assembly, which is attached to the frontplate
• gas train and/or oil supply system, which are connected to
the burner
Rigging —
Rigging should be used to position both the
front plate assembly and the burner assembly because of their
weights. Refer to the shipping container or paperwork for
the weight of these units. For the front plate, either webbed
strapping placed around the refractory can or a lifting bar in
the center opening may be used.
IMPORTANT: Be careful that the assembly does not
slip off.
For burner assemblies which do not have lifting lugs, place
webbed strapping around a central balance area of the burner.
IMPORTANT: Be careful to avoid damage to small
piping, controls, or wiring.
Frontplate and Burner Installation
To prevent leak-
age of high-temperature combustion gases with this type of
forced draft burner, a high-temperature insulating gasket or
1/2-in. Fiberfrax® rope seal is required between the genera-
tor and the front plate assembly, and between the front plate
and the burner assembly.
Either the gasket or the rope may be provided with the
burner, depending on manufacturer’s availability.
When using high-temperature insulating rope, it must
be wrapped around the flange circumference INSIDE of
the mounting studs or bolt holes, with overlapping ends,
to provide a complete gas tight seal. Wrapping the rope
around the outside of the studs or bolt holes could allow
high-temperature gas leakage through the holes in the
attached plates.Use either gasket cement or masking tape
to hold the ropes in place during installation of the front
plate and burner assemblies.
1. Place the high-temperature gasket or insulating rope on
the generator mounting flange, inside the bolt holes.
2. Position the frontplate and refractory assembly against the
generator mounting flange, with the refractory can ex-
tending into the generator fire tube. Secure in place with
washers, nuts, and bolts.
3. Place the high-temperature gasket or insulating rope on
the frontplate flange, inside the studs.
4. Position the burner assembly with the burner head ex-
tending into the front plate and refractory assembly, mak-
ing sure it is plumb. Secure in place with the retaining
lugs on the frontplate studs to ensure a rigid mounting.
Keep the control panel door closed during the burner in-
stallation to avoid damage. Also, it is good practice to
remove the flame safeguard chassis during installation and
to store it in a safe, dry place until start-up.
5. Measure and fabricate burner support pedestal from pipe(s)
with pipe thread on both ends. Screw the support pipe
into the support receptacle, and then screw the opposite
end into the collar that is welded to the underside of the
burner housing. Adjust or shim until the burner is level
and firmly supported.
